Trying to get a look at the Reiser 4 sourcecode for a class assignment.
We are interested in the Tree Structure, Tree Balancing, and Reiser's
use of compression.
However, the how-to, namesys.com for d/ling the code using BitKeeper is
outdated according to the BitKeeper people. Can someone t

There have been some discussions about recovery abilities during
power loss if write cache is enabled. Some recovery tool I saw once
used NVRAM to store progress info so that if you had a power loss it
would be able to resume.
Perhaps it would be possible for Reiser4 to store some info,

Hello,
I was interested in testing the repacker statistics tool that Piotr
Neuman wrote (and others later added to). But from what I can see
the repacker is disabled in 2.6.9-rc4-mm1, because of this patch:
http://kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.9-rc4/2.6.9-
I have a suggestion about the repacker output. Currently the
repacker shows something like this:
Repacker: I am alive, pid = 7716
reiser4 repacker: 4395 formatted node(s) processed, 16858 unformatted node(s)
processed, ret = 0
What I'd like to see is that both lines contained which device

I am thinking that is there was a proper API for accessing the
filesystem then this problem wouldn't arise because things could be
done behind the curtains inside the API, instead of having all the
tools to be rewritten to know.
Think of FAT32, for example, the new filenames wi
